GitHub Action
Backport Action
v8.9.2
Create a file /.github/workflows/backport.yml with the following content:
on:
pull_request_target:
types: ["labeled", "closed"]
jobs:
backport:
name: Backport PR
runs-on: ubuntu-latest
if: |
github.event.pull_request.merged == true
&& contains(github.event.pull_request.labels.*.name, 'auto-backport')
&& (
(github.event.action == 'labeled' && github.event.label.name == 'auto-backport')
|| (github.event.action == 'closed')
)
steps:
- name: Backport Action
uses: sqren/backport-github-action@v8.9.2
with:
github_token: ${{ secrets.GITHUB_TOKEN }}
auto_backport_label_prefix: backport-to-
- name: Info log
if: ${{ success() }}
run: cat /home/runner/.backport/backport.info.log
- name: Debug log
if: ${{ failure() }}
run: cat /home/runner/.backport/backport.debug.log
Now, to backport a pull request, simply apply the labels auto-backport and backport-to-production. This will automatically backport the PR to the branch called "production" when the PR is merged.
For more fine grained customization, and for the ability to run the Backport Tool as a CLI tool locally, you should create a .backportrc.json file in the root directory:
// .backportrc.json
{
// example repo info
"repoOwner": "torvalds",
"repoName": "linux",
// the branches available to backport to
"targetBranchChoices": ["main", "production", "staging"],
// In this case, adding the label "backport-to-production" will backport the PR to the "production" branch
"branchLabelMapping": {
"^backport-to-(.+)$": "$1"
}
}See the Backport Tool documentation for all configuration options.
